Can be injected outside.
　このロック部１５の外周面には突状部２６が複数設けられているために、ロック部１５を押下部１２から取り外す際に便利なものと成る。
　そして、容器開封後使用中の際には、このロック部１５を基礎部１１と押下部１２との間に嵌合することにより、これを押下部１２のロック手段として使用することが可能となるのである。 Since a plurality of protruding portions 26 are provided on the outer peripheral surface of the lock portion 15, it is convenient when removing the lock portion 15 from the pressing portion 12.
When the container 15 is in use after being opened, by fitting the lock portion 15 between the base portion 11 and the pressing portion 12, it can be used as a locking means for the pressing portion 12. It is.
　以下、本発明に係る噴射ボタン１０の製造方法について説明する。
　本発明に係る噴射ボタン１０は、外型と内型の１組の金型を用いて一体的に成形して製作することができる。
　即ち、外型と内型の１組の金型を用いて合成樹脂を充填して一体成形するために、図２（Ｂ）に示した通り、第１ゲートＧ１と第２ゲートＧ２を設け、前記第１ゲートＧ１は、押下部と基礎部に樹脂を充填でき、第２ゲートＧ２は、ロック部１５に樹脂を充填できる。
　そして、第１ゲートＧ１から充填される樹脂は、複数の内部ゲートＧ３を介して押下部１２及び基礎部１１の両者へと充填されるのである。
　この内部ゲートＧ３が成形用接続部として、次の図３の底面図で説明するが、４箇所設けられている。 Hereinafter, the manufacturing method of the injection button 10 which concerns on this invention is demonstrated.
The injection button 10 according to the present invention can be manufactured by integrally molding using a pair of molds of an outer mold and an inner mold.
That is, as shown in FIG. 2 (B), a first gate G1 and a second gate G2 are provided in order to fill a synthetic resin and integrally mold using a pair of molds of an outer mold and an inner mold. The first gate G1 can fill the pressing part and the base part with resin, and the second gate G2 can fill the lock part 15 with resin.
The resin filled from the first gate G1 is filled into both the pressing portion 12 and the base portion 11 through the plurality of internal gates G3.
Although this internal gate G3 will be described with reference to the bottom view of FIG. 3 as a molding connecting portion, four locations are provided.
　図２（Ａ）は、金型内の状態を示す側面側縦断面図を示し、成形完了して離型した状態を図２（Ｃ）が示している。この（Ｃ）図から良く解る通り、離型後、３つの構成要素である基礎部１１、押下部１２及びロック部１５は、組み立てられた状態で、つまりアッセンブリが完成した状態で同時に成形されるのである。
　このアッセンブリが完成した状態において、つまり金型を分離した状態で前記内部ゲートＧ３となっていた成形用接続部は、切断された状態となる。
　図２（Ｄ）は、金型離型後、噴射口部１２ｎが収縮により下方に少し湾曲するが、この収縮曲がり状態を単に図示したものである。 FIG. 2 (A) shows a side longitudinal sectional view showing a state in the mold, and FIG. 2 (C) shows a state where the molding is completed and the mold is released. As can be seen from FIG. 3C, after the mold release, the three components, that is, the base portion 11, the pressing portion 12, and the lock portion 15 are molded in the assembled state, that is, the assembly is completed at the same time. It is.
In a state where this assembly is completed, that is, in a state where the mold is separated, the molding connecting portion which has become the internal gate G3 is cut.
FIG. 2 (D) merely illustrates this contraction bent state, although the injection port 12n is slightly bent downward due to contraction after the mold release.
　図３は、上記実施形態に係る噴射ボタンの底面図であり、この図から成形用接続部、即ち内部ゲートＧ３を見て取ることができる。
　このように、押下部１２の下方筒体部１２ｃを基礎部１１と接続するため、成形用接続部、つまり内部ゲートＧ３が、押下部１２と基礎部１１とを４つの成形用接続部Ｇ３、Ｇ３、…として接続しているのである。 FIG. 3 is a bottom view of the injection button according to the above-described embodiment. From this drawing, the forming connection portion, that is, the internal gate G3 can be seen.
In this way, in order to connect the lower cylindrical portion 12c of the pressing portion 12 to the base portion 11, the forming connecting portion, that is, the internal gate G3, the pressing portion 12 and the base portion 11 are connected to the four connecting portions G3, It is connected as G3,.
　尚、図２（Ｂ）においては、成形用接続部（内部ゲートＧ３）の図示は、図３の位置と整合していないが、成形用接続部を明瞭に示すために、その位置を変更して図示している。また、図２（Ｃ）の縦断面図においては、その左半分の断面は噴射ボタンの中心線と突出部２６を含む面の断面を示し、その右半分は噴射ボタンの中心線と成形用接続部（内部ゲートＧ３）を含む面の断面を示している。
　このように、成形用接続部Ｇ３は、基礎部１１の内壁上端部と押下部１２の下方筒体部１２ｃとの間に４つ介在させている。 In FIG. 2B, the molding connecting portion (internal gate G3) is not aligned with the position in FIG. 3, but the position is changed to clearly show the molding connecting portion. Are shown. In the longitudinal cross-sectional view of FIG. 2C, the left half section shows the cross section of the surface including the center line of the injection button and the protrusion 26, and the right half thereof shows the center line of the injection button and the connection for molding. The cross section of the surface containing a part (internal gate G3) is shown.
As described above, four of the forming connection portions G3 are interposed between the upper end portion of the inner wall of the base portion 11 and the lower cylindrical portion 12c of the pressing portion 12.
　金型に合成樹脂を充填して、固化した後に、内型を取り除くことにより、これら成形用接続部Ｇ３は何れも切断されることとなるものである。
　以上により、本発明に係る噴射ボタン１０は、その構成要素の全てが同時に一体的に成形され、離型時には、その全体が組み立てられた状態で、アッセンブリが完成した状態で出来上がることとなるのである。 After filling the mold with a synthetic resin and solidifying it, the inner mold is removed to cut off any of these molding connecting portions G3.
As described above, the injection button 10 according to the present invention is formed in a state in which all of the components are integrally molded at the same time and the assembly is completed in a state where the whole is assembled at the time of mold release. .
